input field moving selection point

[ericflash]

I have a situation where a user types .5 into an input textfield. What I'm trying to do is change that to 0.5 after they type the .5
In my textfield onChange event I have

		var firstCharacter:String = text.charAt(0);
		if( firstCharacter=='.' ){
			trace("text = "+text);
			text = '0' + '.';
			Selection.setSelection(  1, 1  )
		}

What I'm trying to do up here is when the user types "." it changes to 0. then I need to move the cursor 1 place passed the the decimal so the user can type in there after the decimal numbers.

Ok the answer to this one is flash is stupid.
How about this flash has a slight delay in updating its textfields so I had to add a delay before I called the Selection.setSelection( 2, 3 )
